Simple production of diamond rod
« on: December 20, 2016, 10:40:21 AM »

It feeds a 1 cm graphite finger with an electric welding machine,
gradually increasing the current until the rod starts to glow;
at this point it sprays CO2 on the finger which should become translucent.

Carbon dioxide will oxidize the graphite rod under formation of highly poisonous carbon monoxide.
